2 mandatory
5.5 mandatory
6 supported
9 supported
11 mandatory
12 supported
is this correct after modified:
1 disable

802.11g devices will be supported. All rates below the Mandatory rate should be disabled, so set 12 mandatory.

In my 2.4 Ghz & 5.0 Ghz deployment, I have 1- to 11 Mbps disabled, 18-, 36- and 54 Mbps set to Mandatory.
We also made a network-wide policy that any wireless client that do not adhere to this settings will not be allowed -- And we have told several business units that we are no longer "bending over backwards".

our issue is coverage, can't reduce data rates too much
